If someone tells you about some new improvement to a program, you
might respond: “Feetch, feetch!” The meaning of this depends
critically on vocal inflection. With enthusiasm, it means something like
“Boy, that's great! What a great hack!” Grudgingly or with
obvious doubt, it means “I don't know; it sounds like just one more
unnecessary and complicated thing”. With a tone of resignation, it
means, “Well, I'd rather keep it simple, but I suppose it has to be
done”.
